IMPROVETMENT IN STRAW-CUTTERS.

The Schedule referred'to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, L. B. HYATT, of Flemington, in the county of Clinton, and State of Pennsylvania, have invented a new Vand useful Improvement in Straw-Cutters; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, 4reference bcinghad to the accompanying drawing, forming part of this specification.

'Ihis invention relates to mprovementsin the oonstructionV of straw-cutters, the object of which isv to provide a more durable pivot-point for the hand-vibrating cutter-lever; also to prevent lateral play of the said lever on the point, all as hereinafter more fully specified.

Figure l represents a perspective view of a cutter, constructed according to my improvements, and

Figures 2 and 3 represent detail views of the same.

Similar letters of reference indicate corresponding parts.

A represents a metallic-plate for the end of the box, having an opening through it, for the passage of the straw, on the bottom wall, B, of which 'the vibrating cutter acts to cut the straw.

This plate has a projection at one end, for supporting the axial bolt of the vibrating cutter-arm C.

My invention consists in casting a hollow stud, D, on this plate for the axis of the said lever, whereby the wearing-surface may be large and hard, and a small'bolt may be passed through for holding thelv lever thereon by a washer and nut, as shown at E.

To prevent lateral vibration of the cutter-arm, l provide, also, by casting au annular-collar, F, around 'the said stud; also a circular springbearing, G, in a cur-"ed slot near the end of the plate A, and a projection, H, on the lever, beyond the axis.

The bearing G is made yielding, by rubber springs interposed in the slot behind it; and to prevent the said bearing from falling ont, I form a curved flange, I, at the end of the said plate.

This arrangement provides a much more durable machine, and confines the knife with a strong pressure against the margin of the opening through the plate A, but capable of yielding to some extent, and thereby preventing too great friction between the two.

Having thus described myinvention,

\Vhat I claim as new, and desire to secureby Letters' Patent, is

1. The plate A, provided with the hollow axial-pin D, annular collar F, and yielding-guide G, substantially as specified.

2. The cutter-arm C, provided with the projection H, and combined with the plate A, when the latter is arranged substantially as specified.

3. The combination, with the vibrating cutter-arm, of a yielding bearing, G, substantially as specified.

lVitnesses:

HUGH Dnvnrne, J. W. DnvLIsG.
